Application filed August 19, 1922. Serial No. 583,027.

To all whom it may concern:

Be it known that I, PHILIP H. Mo- DERMOTT, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Oil Collectors for Tool Stocks, of which the following is a specification.

This invention relates to oil collectors for tool stocks. K

Tool stocks of the kind with which my invention is adapted to be incorporated consist of a central head which carries the threading or cutting dies, and a pair of diametrically disposed handles extending from said head. In using the stock the threading ,dies are first arranged upon the work and the stock revolved by means of the aforesaid handles. During an operation of the stock, it is necessary to frequently supply the cutting dies with lubricating oil. Due to the fact that the stock is constantly revolving around its work, this lubricating oil flows from the head of the stock and soon trickles down on to the handles, making it necessary for the user to constantly wipe the handles to relieve same of the accumulated oil. This requires time and through the fact that the oil is once permitted to lodge upon the handles, it is difficult for an operator to control the tool without his hands slipping from the handles. Should one be standing near the operator when his hands slip from the tool he may be suddenly brought into contact with the operator with serious consequences.

An object of my invention is to provide an oil collecting device for revolving tool stocks, the device consisting of cups arranged upon the diametrically disposed handles and constructed so as to catch the oil as it flows from the head of the stock and prevent the oil from actually passing onto the hand gri s or actuating surfaces of the handles, there y maintainin the actuating portions or grips of the handles in a dry state at all times and enabling the operator to obtain firm purchase of the hands thereagainst.

Another object of the invention is to provide a device of this character consisting of handle engagin cups, each provided with a pluralit of we s, one of which operates to collect t e oil in one position of the handle and the other to arrest return of the oil to the stock, except for a small charge which is purposely permittedlto return to the illustrated in the accompanying drawing, 1

in which j Figure lis a plan view of a stock showing the invention applied thereto.

Figure 2 is avertical section through one of the cups applied to the handle of the stock.

In the drawing 5 indicates the customary head of a stock. Extending from the head at diametrically opposite positions thereon are handles 66, each provided with an active manipulating portion or grip 7. t

On each handle at a point near its juncture with the head 5 is a cup 8.

Each of these cups is formed preferably from a single casting so as to provide a chamber 9 which is sub-divided into an outer well 10 and an inner well 11. The walls of the inner well are curved inwardly at 12 toward the handle and then downwardly at 13 in substantially parallel relation to the handle and for a distance approximating one-third of the entire length of the cu The wall 13 is slightly spaced from the wal s of the handle so as to form an annular channel 14; around the handle. The opposite end or well 10 of the cup has its walls formed into an embracing sleeve 15 which encircles the handle. This sleeve is provided with an annular rubber gasket 16 which bears against the walls of the handle so as to seal the joint between the cup and the handle and positively prevent any escape of oil onto the manipulating portion or grip end of the handle. To secure the cup firmly upon the handle use is made of means 17 in the form of a set screw adjustable in the sleeve 15 and adapted for clamping engagement with the handle.

By curving the wall 12 into the wall 13 and by spacing the latter from the walls of the handle oil is permitted to flow into the cup as the tool revolves. Adhesion of the oil against the surfaces of the handle and the walls 13 opposite the handle causes the oil to flow in a constant straight line with respect to the handle and in practice it is found that any tendency of the oil to pass over the wall 12 and downward upon the exterior of the cup is entirely eliminated. From the construction described it is seen that as the stock revolves oil is permitted to pass into the cup when the handle revolves where it may be collected by the cutting dies 7 and reused.

lVhile I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details. of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

What is claimed as new is 1. The combination with a tool stock, of cups mounted on the handles of the stock and each having a plurality of communicatingwells, the Walls of one of the wells of each cup being curved inwardly toward the adjacent handle and then extended along one side of the handle in spaced parallel relation thereto. r

2. The combination with a tool stock, of cups mounted on the handles of the stock and each having a plurality of communicating Wells, the walls of one of the wells of each cup being curved inwardly toward the adjacent handle and then extending along one side of the handle in slightly spaced parallel relation thereto.

3. An oil collector comprising a cup having a sleeve for sealing contact with a handle, a plurality of wells formed in the cup, the walls of one of the wells provided with a portion ada ted to be arranged in spaced relation to the handle.

4. An oil collector comprising a cup having a plurality of wells, a sleeve formed on the cup at one end thereof, said sleeve adapted to accommodate a handle and means for sealing the sleeve "against the handle.

5. An oil collector comprising a cup havinga plurality of wells, a sleeve formed on the cup at one end thereof, said sleeve adapted to accommodate a handle and means for sealing the sleeve against the handle, and

means on the sleeve for securing the cup to the handle.

In testimony whereof I have aifixed my signature.
